4.35 Two adults and a child want to push a wheeled cart in the direction marked x in the figure. The two adults push with horizontal forces F1 and F2 as shown. (a) Find the magnitude and direction of the smallest force the child should exert. Ignore the effects of friction. (b) If the child exerts the minimum force found in part (a), the cart accelerates at 2m/s2 in the +x-direction. What is the weight of the cart?
